Chemical energy into light energy
more specifically
i.e. dry cell converts chemical energy into electrical energy
flashlight converts electrical energy into light energy
A battery is the electrochemical cell is used as an energy source in a flashlight.
A Dry Cell
Zinc
The process is called photosynthesis it is used by plants to get their energy and make food using chlorophyll.Photosynthesis converts light energy into chemical energy.
photoconductive polymers are materials that change their electrical conductivity when subject to light (infra red- visible - ultraviolet - gamma). They are mainly used in photocopiers and holography.

Dry-cell
The light produced by a flashlight is electromagnetic radiation.
A Dry Cell
yes
Chemical ----> Electrical --------> Light
flashlight is always lighting for people in dark. There are other more applications from differrent color light, such as imalent flashlight, spot light is for daily use, UV light can check ID card or ticket, red light can be used warning in traffic.
it is used as the backing reflector for the bulb. because it is concave, the light that hits it is focused into a beam of light.
to convert electricity into light
When you shine a flashlight at a mirror it proves that you are able to turn the flashlight on. The reflection of that light can be used to demonstrate some basic principles of optics, such as that the angle of incidence equals the angle of reflection. It proves that the flashlight is in working order, that you are able to direct the light toward the mirror, that the light is reflected by the material at the back of the mirror, that the mirror itself is opaque, and that you have access to a mirror and a flashlight.

Concave Mirrors, so that the light can be concentrated and so that it points forward. This is how we are able to see using a flashlight beam.:) Catherine
